Abstract

 
 
 Water-in-diesel emulsion fuel (W/D) is an effective method for reducing emission of nitrogen oxides (NOx) from a diesel engine. However, the current approach of producing W/D has its disadvantages in terms of cost and complexity. Therefore, a new approach to produce W/D is developed where water is introduced in vapour state, instead of as liquid, into the fuel. This new method may simplify the emulsion production process as it requires less mechanical parts than any previous non- surfactant emulsion forming methods. The objective of this study is to determine the physical characteristics of steam generated W/D and its engine emission. The characteristics to be determined include the size distribution of water droplets as well as water content. Engine emission will be measured from a 5 kW single cylinder, direct injected, air cooled diesel engine.
